EYEGLASSES OR SPECTACLES.

SPECIFICATION forming part O' Letters atent No. 766,418, dated August 2,1904.

.application `filed August 6, 1903.

To @ZZ 10h/mt it #my concern:

zen of the United States. residing at Elizabeth, in the county ot' Unionand State ot New Jersey, have invented certain new and usefulImprovements in Ilveglasses or Spectacles, ot' which the following' is aspecilication` such as will enable those skilled in the art to which itappertains to make and use the saine.

rlhe objcctotl this invention is to provide an improvement in eyeglassesand spectacles whereby a pair of spectacles may be easily converted intoa pair of eyeglasses whenever desired and whereby a pair ot' eyeglassesmay also be converted into a pair of spectacles whenever desired; andwith these and other objects in view the invention consists in theconstruction, combination, and arrangement of the parts in connectionwith eyeglasses and spectacles hereinafter described and claimed.

The invention is 'tully disclosed in the t'ollowing specilication, otwhich the accompanying drawings form a part, in which the separate partsot' my improvement are designated by suitable reference characters ineach ot' the views, and in which-- Figure 1 is a perspective view ot' apair ot' eyeglasses provided with my improvement; Fig. 2, a view of apart otl Fig. l on a larger scale. Figs. 3 and -I are views similar toFig. Q, but showing moditication. Figs. 5 and (3 are views showing apart of the frame of a pair of spectacles on an enlarged scale.

In the practice ot' my invention as shown in Figs. l and 2 I provide apair ot' eyeglasses comprising the separate glasses u. connected by theusual nose-piece which is provided with the usual nose-clips c. The endsot' the glasses c opposite the spring are provided with clips (l, havinga transverse member or bar tlg, provided with inwardly-directed lingers(Z3, and I also provide spring side arms or bows fr, which are adaptedto engage the ear in the usual manner and which are composed ofspring-wire bent to `t'orm a ring or coil 25, a central ring or coil f,and a supplemental ring or coil fj, and in practice the srn'ing rings orcoils and if" are pressed together and inserted between the ends of thesel-isi No. 163,395. (No moda tingersf/, after which they expand andengage Be 1t known that l, Amar. I). BLocn, a citisaid lingers, asclearly shown in Fig'. 2. By means of this construction the said arms orbows ff may be attached to or detached from the eyeglasses wheneverdesired, and the said glasses may thus be used in the ordinary manner oras a pair ot' spectacles whenever necessary. ()ne of the coils 2 andpreferably coil wg, is provided with a backwardly-directed member orfinger ff", which presses on the cross-bar f/f and prevents the arms orbows l from swinging `backwardly too far.

.ln the construction shown in Figs. l and 2 the cross bar or member Jiis Vformed integrally with the clip (Y, and this clip must theretore bemade especially for this purpose; but in the construction shown in Fig.3 I secure the cross-bar d to the clip and the ordinary clip may beemployed.

The construction shown in Fig. 4 is similar to that shown in Fig. 3 withthe exception that the cross-bar r/2 is provided at its ends withextensions which take the place of the inwardly-directed lingers f/l,and in this form ot' construction the rings or coils ff" and f arepressed apart and allowed'to engage the members when they contract; butthe operation of the said arms or bows f will be su bstantially the samewith either ot' these forms otl construction.

In Figs. and 6 l have shown a part of the frame of a pair otl spectaclescomprising the usual frame members f, in which the glasses are placed,and in this form ot' construction the said trame members are provided attheir outer ends with angular and inwardly-directed fingers f' and thearms or bows f are connected with the lingers in the same manner as inthe construction shown in Figs. I and 2, and this form ot' theimprovement may be applied either to eyeglasses or spectacles, as may bedesired. In the form ot' construction shown in Fig. 6, however, Ylemploy the ordinary side bow or bar the attached end of which is slitlongitudinally to form two spring members or fingers 'i, provided attheir ends with eyes or rings which in practice are compressed, so as topass through the lingers i, after which they are allowed to expand andengage said ingers or linger-pieces, or the ally-arranged lingers, andside arms or bows provided` with laterally arranged spring/ I 5 catchesadapted to engage said fingers, substantially as shown and described.

In testimony that I claim the Jforegoing as my invention I have signedmy name, in presspring members or fingers k2 may be made to operate asshown in Fig. 4C. l

Having fully described my invention, what l I claim as new, and desireto secure by Letters i Patent, is-

l. A pair or' eyeglasses the outer ends of which are provided with theusual clips having'laterally-arranged fingers, and side arms l ofAugust, 1903.

or bows provided with laterally-arranged 1 spring-catehes adapted toengage said fingers, ABEL D' BLOCH' substantially as shown anddescribed. 2. A pair of eyeglasses or spectacles, the
